getchar reads a single character from standard input. The character is
converted to unsigned char before being returned; thus, EOF, which is
negative, is not a possible successful return value.

On success, getchar returns the character read. On error, or end of
file, EOF is returned.

<h3>Errors</h3>

Any of the errors associated with <A HREF=../syscall/read>read</A>
may occur.
